The star further explained: "I love his stuff, so I said, 'Look, I live in New York. If you ever have anything'… So he called me [last week] and said, 'I have this idea.' I was like, 'Great.' 'Val Kilmer's in it, too.' 'Terrific.' We had a ball. We laughed a lot."

Damon was also impressed by his 'Digital Short' co-star Perry, who made her hosting debut on Saturday's show.

"[She's] funny and really cool. It was the first time I met her and she was great," he added.

Damon hosted SNL in 2002, but had not returned to the program in nearly a decade prior to last weekend's cameo.

Saturday Night Live continues this weekend with host Jimmy Fallon and singer Michael Buble at 11.30/10.30c on NBC.
